In 2004-2006 she was a General Manager's assistant at a private hospital in Berlin, being also responsible for the activities and businesses of the hospital related to the East European states.

Dr. Joerg-R. Kropp

/ Director of Integration Technologies and Packaging
Dr. Joerg-R. Kropp received the doctor of science in the field of atomic physics with optical spectroscopy and laser applications. He gained over 25 years of industrial experience in the field of optical communications through various management positions with Siemens and Infineon. His field of experience includes the development of manufacturing processes for mass production of optical transceivers, the development of new generations of modules (such as the well-known parallel optical modules from Siemens PAROLI) as well as innovation and patent management and technology and IP analysis. In addition, Dr. Kropp actively participated for over 10 years in the development of various LAN standards of the optical Ethernet. Dr. Kropp is the inventor of over 40 patent families, with patents in different countries and author of numerous publications and technical contributions in the field of optical communications and micro-systems technology.

Emil Abelaf

/ Director of Business Development
Emil Abelaf has over 25 years in Sales, Marketing, and Technology and Business development in the fiber optics industry. He developed some of the first digitally driven fiber optic receivers and transmitters as well as the first commercially viable Fiber Amplifier.
He has driven very high revenue growth in many companies, including BT&D Technologies, (purchased by HP/Agilent), E-TEK Dynamics, JDS and SDL, and worked closely with the senior management of those companies to make those companies very successful. He has also managed sales organizations that spanned North America, Europe and most of Asia.
Mr. Abelaf graduated with a Bachelors of Science of Materials Science from Cornell University.

VI Systems GmbH is a German technology company that specializes in the development and manufacturing of high-speed optical components and modules for data communications and sensing applications.
